OSLO (Reuters) - German Foreign Minister Frank-Walter Steinmeier said on Sunday he hoped a new regulation aimed at maintaining a fragile ceasefire in eastern Ukraine could be completed soon by the Organisation for Security and Cooperation in Europe (OSCE).

"We are working with the OSCE for a new regulation to keep the ceasefire," Steinmeier told reporters in Oslo. "We are now in preparation which will allow us to soon meet again on the foreign ministers’ level."

Steinmeier said implementation of the Minsk accord by Russia and Ukraine remained disappointing, and the security situation in eastern Ukraine was "really insufficient."
